From d6023d33a4ac9bc53975c9029a59135d71a76268 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Mon, 17 Oct 2016 13:44:09 -0200 Subject: [PATCH] [media] v4l: rcar-fcp: Fix module autoload for OF registration If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/media/platform/rcar-fcp.ko | grep alias alias: rcar-fcp After this patch: $ modinfo drivers/media/platform/rcar-fcp.ko | grep alias alias: rcar-fcp alias: of:N*T*Crenesas,fcpvC* alias: of:N*T*Crenesas,fcpv alias: of:N*T*Crenesas,fcpfC* alias: of:N*T*Crenesas,fcpf Signed-off-by: Javier Martinez Canillas Reviewed-by: Laurent Pinchart Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/rcar-fcp.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/media/platform/rcar-fcp.c b/drivers/media/platform/rcar-fcp.c index f3a3f31cdfa9..7146fc5ef168 100644 --- a/drivers/media/platform/rcar-fcp.c +++ b/drivers/media/platform/rcar-fcp.c @@ -169,6 +169,7 @@ static const struct of_device_id rcar_fcp_of_match[] = { { .compatible = "renesas,fcpv" }, { }, }; +MODULE_DEVICE_TABLE(of, rcar_fcp_of_match); static struct platform_driver rcar_fcp_platform_driver = { .probe = rcar_fcp_probe, -- 2.39.5
